Antimicrobial Activity

According to the method outlined by Elsebaie and Essa [62], the antimicrobial activity of the prepared gel films was assessed against two Gram-positive, *Bacillus subtilis* ATCC21331 and *Pseudomonas aeruginosa* (CGMCC1.8721), and two Gram-negative, *Escherichia coli* ATCC25921 and *Salmonella typhimurium* (CGMCC 1.10754), bacteria. A movable calliper was used to measure the inhibitory zone.
